Custom High-Frequency Transformer

We design and manufacture custom transformers for a wide range of industrial and electronic applications. From specification review and prototype development to mass production, our engineering team works closely with you to deliver transformers that match your exact electrical, mechanical and environmental requirements.

 

Product Range

Power Transformers Reliable power conversion for industrial equipment, control systems and electronic devices.

Toroidal Transformers Compact, low-noise design with low electromagnetic interference — ideal for audio, medical and precision equipment.

EI / Laminated Core Transformers Cost-effective, robust solution for power supplies and general electronic applications.

High-Frequency Transformers Ferrite-core designs optimized for switch-mode power supplies, drivers and DC/DC converters.

Current Transformers Accurate current measurement and monitoring for meters, drives and protection systems.

Isolation Transformers Enhanced safety and noise isolation for sensitive and medical-grade equipment.

Audio / Signal Transformers Clean signal transmission with low distortion for professional audio and communication devices.

 

Customization Capabilities

Every custom transformer is built to your specifications. We can customize:

• Power rating, input / output voltage and frequency

• Core type, size and mounting configuration

• Winding materials, insulation class and temperature rise

• Enclosures, leads, connectors and terminal options

• Compliance with UL, CE, RoHS and other standards as required

High-Frequency & Precision Design

Beyond standard power transformers, we manufacture high-frequency custom transformers for performance-critical applications. Our capabilities include:

• Litz wire windings for reduced skin effect and lower AC losses at high frequencies

• Ferrite core designs (E-type, toroidal and other geometries) with precisely controlled winding structures

• Vacuum resin impregnation for superior insulation, mechanical stability and long-term reliability

• Interlayer insulation engineering for reliable high-voltage isolation between windings

Full Electrical Verification on Every Unit

Every transformer we produce is 100% electrically tested before shipment:

• Inductance verification

• Quality factor (Q) measurement at operating frequency

• Self-resonance frequency (SRF) testing

• Insulation / hipot and turns-ratio checks

This ensures every unit performs identically to the approved sample — not just on the day it ships, but across the entire production run.

 

Applications

Our transformers are trusted in performance-critical equipment, including:

• Medical ultrasonic devices

• Industrial power and control systems

• Precision instrumentation

• Power supplies and DC/DC converters

• Audio equipment

• LED drivers and renewable energy systems

How It Works

1. Send Your Requirements Share your specifications, drawings or even a sample — our engineers will review them and reply within 24 hours.

2. Design Review & Quotation We confirm the technical solution, materials and cost, and provide a formal quotation.

3. Prototype & Verification Samples are built and fully tested. You approve the electrical performance before mass production.

4. Mass Production & Delivery Controlled production with 100% final testing ensures consistency from the first unit to the last.
 

FAQ

Q: What is your minimum order quantity for custom transformers? A: We support low-volume prototype orders and scale smoothly to mass production. Contact us with your requirements for details.

Q: Can you work from a sample instead of a drawing? A: Yes. Send us the sample and we can analyze it, reproduce the winding structure and propose an improved or cost-optimized version.

Q: How long does a custom design take? A: Standard custom designs typically take 1–3 weeks from specification to verified samples, depending on complexity.

Q: Do you provide test reports? A: Yes. Full electrical test data (inductance, Q, SRF, hipot) can be provided with every shipment.
